Abstract
Some embodiments of the present disclosure include a tool set for the installation and removal of a gasket from a hose. The tool set may include a gasket insertion tool configured to install a gasket on a hose, the gasket insertion tool being self-centering and having a plunger foot configured to install the gasket onto the hose. The tool set may also include a gasket removal tool configured to remove a gasket from a hose, the gasket removal tool being self-centering and including at least one blade configured to grab onto the gasket to remove the gasket from the hose.
Claims4
A gasket insertion tool configured to install a gasket on a hose, the gasket insertion tool comprising:
- a hollow insertion barrel having an unsealed threaded end configured to accommodate a gasket and configured to engage with threads on a hose coupling;
- a plunger extending from an end of the hollow insertion barrel distal from the threaded end, the plunger configured to slide along a length of the hollow insertion barrel within the hollow insertion barrel;
- an interior of the hollow insertion barrel comprises a lip configured to prevent the plunger foot from being removed from the interior of the hollow insertion barrel;
- a spring positioned around the plunger and extending from an area proximal to the lip to a position proximal to an end of the plunger distal from the plunger foot;
- and
- a cap attached to the distal end of the plunger, the cap being configured to prevent the spring from sliding off of the plunger;
- wherein
- the plunger comprises a plunger foot slidably secured within the hollow insertion barrel;
- and the plunger foot is configured to slide from an area proximal to a center portion of the insertion barrel's length towards the threaded end, placing pressure on the gasket and forcing the gasket onto the hose;
- wherein
- the cap is secured to the plunger via a roll pin extending through a pair of cap pin holes and a plunger pin channel in the plunger.
A gasket removal tool configured to remove a gasket from a hose, the gasket removal tool comprising:
- a removal barrel having an unsealed threaded end configured to accommodate a gasket and engage with threads on a hose coupling;
- a cutter extending from an end of the removal barrel distal from the threaded end, the cutter configured to slide along a length of the removal barrel within the removal barrel;
- at least one blade positioned at an end of the cutter proximal to the threaded end, the blade being configured to grab onto the gasket to remove the gasket from the hose;
- and
- a spring positioned around the cutter and extending from an area proximal to a lip in an interior of the removal barrel to a position proximal to an end of the cutter distal from the at least one blade.
